Let''s say we have a point K=(Kx, Ky, Kz). Now we move through point M=(Mx, My, Mz) to the point L=(Lx, Ly, Lz). And now I want to move the vector KL in reverse direction that the point L is in M point, but I don''t know how to calculate K position.

Hi TheVoid,

Can you please restate your question? Your second sentence is a bit confusing. You are trying to calculate K? But your first sentence said that you already have a point K? And you moved from point M to point L, but ended up with vector KL? Why wouldn''t this be vector ML?

A diagram would be helpful!

I''m closing this thread because there are two later threads seem to ask exactly the same question. And those two threads provide some images that explain the problem better.
